Asbestos Removal Process
1. Project Assessment
Initially, we assess the specific type of abatement (asbestos removal) required to ensure the safe removal of asbestos. In Ottawa, Ontario, there are three classifications of asbestos abatement: Type 1, Type 2, and Type 3. Each successive level necessitates more stringent safety protocols and distinct asbestos removal procedures to adequately manage the associated risks and ensure compliance with regulatory standards.
2. Containment Construction
This phase involves the construction of a secure enclosure around the project area using reinforced polyethylene sheeting. Following this, a three-chamber decontamination unit is constructed at the entrance to the project site to ensure controlled access and egress. Finally, negative air machines are installed to maintain a pressurized containment, ensuring that airborne contaminants are effectively managed and prevented from escaping the work area during the asbestos removal.
3. Asbestos Removal
The removal of asbestos-containing material can now commence. The removal method employed will be determined by the specific abatement classification being implemented.
4. HEPA Cleaning
Once all asbestos-containing material has been removed, the cleaning process begins. The entire project area, including the interior of the containment and decontamination chambers, undergoes a meticulous three-step cleaning procedure. First, the area is thoroughly vacuumed using high-efficiency particulate air (HEPA) vacuums to capture any residual asbestos fibers. Next, the surfaces are wiped down with damp cloths to remove any remaining particles. Finally, a second pass with HEPA vacuums is conducted to ensure the area is completely free of contaminants. The cleaning process is an absolutely critical part of the asbestos removal procedures.
5. Air Testing
Air Testing following an abatement project is only required in Ottawa under O.Reg 278/05 for Type-3 abatement projects. However, any asbestos removal project can undergo air testing. Upon request air testing can be completed.
